Architecture Flow Definitions

hri control data  (Planned )  Applicable ITS Standards

Data required for HRI information transmitted at railroad grade crossings and within railroad operations.

hri request  (Planned )  Applicable ITS Standards

A request for highway-rail intersection status or a specific control request intended to modify HRI operation.

hri status  (Planned )  Applicable ITS Standards

Status of the highway-rail intersection equipment including both the current state or mode of operation and the current equipment condition.

right-of-way request notification  (Planned )  Applicable ITS Standards

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other source for right-of-way.

signal control plans  (Existing)  Applicable ITS Standards

Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.

signal control status  (Existing)  Applicable ITS Standards

Operational and status data of traffic signal control equipment including operating condition and current indications.

traffic flow  (Existing)  Applicable ITS Standards

Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.

traffic sensor control  (Existing)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.
